Abstract (en)

Embodiments of the present invention provide a channel measurement method. The method includes: obtaining, for a to-be-measured frequency band including at least one reporting subband and at least one missing subband, channel state information of each reporting subband and channel state information of each missing subband, where the channel state information of each reporting subband is obtained based on channel estimation, and the channel state information of each missing subband is obtained according to a reference rule with reference to channel state information of a reporting subband that is indicated by the reference rule and that is in the at least one reporting subband; and sending a measurement report of the to-be-measured frequency band to a transmit end device, where the measurement report includes the channel state information of each reporting subband in the at least one reporting subband. The present invention helps reduce feedback overheads brought by channel measurement, and helps implement consistency of the channel state information between a receive end device and the transmit end device, to avoid adverse impact on a transmission effect.
